The Great Sierra River Clean Up is a collaborative effort between the Sierra Foothill Conservancy, Upper Merced Watershed Council, Bureau of Land Management, and the Kim Evans Memorial Clean Up. This is a one day event held annually on the third Saturday of September that brings the community together to help clean up our beloved watershed. Volunteers are needed to help with this effort. Let's make this a cleaner and safer river canyon for families to enjoy.

This annual event takes place every year on the third Saturday of September from 9 a.m. to 1 p.m. in conjunction with the California Coastal Cleanup Day.

Each year participants remove over 2,000 pounds of trash and recyclable material from the Merced River.  The Great Sierra River Clean Up is about much more than picking up trash, however. It’s a day for Sierra communities – and those from all over California – to demonstrate their desire for clean water and healthy rivers.

It’s an opportunity to learn about Sierra rivers and it’s a time to come together with your children, your families, your neighbors, and your friends to accomplish something vital and worthy on behalf of our great Sierra rivers. By volunteering you will become part of a greater restoration effort.
